Original caller ID when line is forwarded to mobile

[NSR]

I have a user who is forwarding calls to their cell phone. When a call comes in, the caller ID shows up as the user's 3CX DID assigned to their office phone, and not the caller's ID.

I have specified "OriginatorCallerID" under "Remote Party ID - Calling Party under Voice & Chat, since I had read on another thread that this resolved the issue. It seems to have made no difference though. We are using Voxtelesys as our SIP trunk provider.

Any thoughts on this one?

Bump? Has anyone encountered this before and know of a potential fix? Or is this just a limitation we will have to live with?
